<p>我的理解：</p>
<blockquote>
<p><code>justify-items</code>和<code>align-items</code>是设置<code>内容区的开始方式</code>，不是内容的对齐方式。默认是 stretch 的效果；</p>
</blockquote>
<p>比如现在一个宽高都是 50px 的正方形区域，默认整个区域都是内容区域，比如设置背景为红色，那回看到一个宽高都是 50px 的正方形，这应该都能理解；</p>

<p>如果设置了<code>justify-items:start</code>(需要启用 grid 模式)，则内容区域则是从左开始，直到够现实内容即可，剩下的就不是内容区域了，比如下面的效果图是每个元素都是 80px 的正方形，但是背景色只是显示了由内容的地方，设置成 stretch 就成了上面的效果了。<br><img src="https://upload-images.jianshu.io/upload_images/1348523-696d314dac297570.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="image.png"></p>
<p>在子元素上设置的<code>justify-self</code>和这个一个意思。</p>
